You could also just do it with traffic. A few cars repeatedly circling the same key intersections would gridlock the city. At least in Atlanta you have the case studies in Freaknik and Snowpocalypse. I'm sure other cities are the same.
true, but the cars aren't rendered inoperable they can be pulled to the side and unless you kept repeatedly doing it once that initial jam clears it's back to normal. Wrecks happen frequently enough that all lanes will be blocked for a period of time throughout the day but traffic still clears quickly once the wreck is removed.
The key is to exploit the preexisting traffic with non-standard traffic. Traffic patterns depend on the fact that people are passing through and moving from point A to point B, not continually occupying a certain stretch. If you had enough vehicles to wrap around a block, all in right / left turn configurations once you're traffic has wrapped end to end a single time it's indefinitely gridlocked.
Take a circular highway like the beltway if you had only about a hundred cars, enough that you could have a vehicle in each travel lane and groups like this spaced out every 10 or so miles, and they just drive slower than normal traffic and never exit. Once the groups start backing into each others artificially created traffic it is basically stuck at gridlock until those people decide to exit.
You could also do the same thing as intersections with select exit / on ramp, if you can back them up with traffic that doesn't intend to exit the loop you only need enough vehicles to "seam" together the normal flows of traffic to fully gridlock the intersection.
I've written papers on business process modeling for traffic, crowd and customer flows it's devastating the effect that non-terminating entities have on the process flow unless they move faster than average. If they move slower their effect is amplified with each successive iteration until failure. Of course that also doesn't matter if there are more non-terminating entities than capacity which results in a single iteration failure.

you can just make caltrops from wood and screws and dump them down the freeway
Hundreds of little tire poppers and suddenly a whole city can’t get to work
Wouldn’t even be hard
Buy a cheap POS pickup truck for cash on craigslist - you could run around for a few weeks doing this then just abandon the vehicle
